50% concentrated water discharge, belong to highly energy-consuming discharge-reducing method；Second, carrying out multiple-effect evaporation, waste water is heated into steam, then be cooled to
Distilled water recycles, and dope discharge or dosing crystallisation solidification, investment is big, and operating cost is high, and consumption heat energy is huge, rarely useful
Adopt at family；Third, being discharged into evaporation pond, evaporation or stratum seepage cause underground water pollution when the sun shines；Fourth, directly discharge the Nature
Rivers,lakes and seas.
3. the processing of desulfurization water is extremely difficult, some enterprises are unordered discharge or drain into municipal wastewater treatment plant processing, some enterprises
Burned during industry incorporation is coal-fired, form vicious circle.Contain suspension, oversaturated sulfate, chlorion, a huge sum of money in desulfurization wastewater
Belong to the heavy metals such as mercury, lead, nickel, zinc, after municipal sewage plant receives desulfurization water, good method is not handled, and is simply diluted
Discharged after turbidity removal.
4. ion exchange resin regeneration acidic and alkaline waste water, acidic and alkaline waste water neutralization has been accomplished by each enterprise, and degree of neutralization is let nature take its course.
Due to the Cl in acidic and alkaline waste water-、SO4 2-And Ca2+、Mg2+Content is high, and pH value is fluctuated, so this effluent part all turns into enterprise
The outer draining of industry.
